During diastole, coronary perfusion depends on the pressure drop between the myocardial tissue and the coronary origin located at the aortic root. This pressure difference is influenced by the flow field near the closing valve leaflets. Clinical evidence is conclusive that patients with severe aortic stenosis (AS) suffer from diastolic dysfunction during hyperemia, but show increased coronary blood flow (CBF) during rest. Transcatheter aortic valve implantation (TAVI) was shown to decrease rest CBF along with its main purpose of improving the aortic flow and reducing the risk of heart failure...

performing percutaneous coronary intervention (PCI) following transcatheter aortic valve implantation (TAVI) will become more frequent with the increasing use of TAVI in lower surgical risk populations. The ideal management strategy for coronary artery disease (CAD) in the setting of TAVI is not well defined and CAD is often left untreated prior to TAVI. Engaging the coronary ostia through the TAVI side cells can be challenging; techniques for rapid coronary cannulation, especially in the acute setting, need to be developed...

Aims: Transcatheter aortic valve implantation (TAVI) is an increasingly common intervention for patients with aortic stenosis deemed high risk for major cardiac surgery, but identifying those who will benefit can be challenging. Frailty reflects physiological reserve and may be a useful prognostic marker in this population. We performed a systematic review and meta-analysis of the association between frailty and outcomes after TAVI. Methods and Results: Five databases were searched between January 2000 and May 2015...

Elastic resistance is a common training method used to gain strength. Currently, progression with elastic resistance is based on the perceived exertion of the exercise or completion of targeted repetitions; exact resistance is typically unknown. This study's objective is to determine if knowledge of load during elastic resistance exercise will increase strength gains during exercises. Participants were randomized into two strength training groups, elastic resistance only and elastic resistance using a load cell (LC) that displays force during exercise...

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) has been demonstrated to be an alternative treatment for severe aortic stenosis in patients considered as high surgical risk. Since its first human implantation by Cribier et al., TAVI has been shown to increase survival rate and quality of life for high surgical risks patients. The objective of this study is to provide an overview of TAVI registries and the reporting clinical outcomes based on the VARC-2 definitions. In addition, the comparability and adherence of VARC-2 reporting within the identified TAVI registries was reviewed...

The purpose of this systematic review and meta-analysis was to assess the 30-days safety (bleeding and vascular events) and efficacy (reduction in major stroke, myocardial infarction and mortality) of single anti-platelet (SAPT) versus dual anti-platelet (DAPT) after transcatheter aortic valve implantation (TAVI). We used a meta-analytic method with Mantel-Haenszel methods to calculate the odds ratio (OR) and 95% confidence interval (CI). Only randomized clinical trials that compared 30-days safety and efficacy based on Valve Academic Research Consortium criteria were included...

Patients with severe symptomatic aortic stenosis have a poor prognosis with medical management alone, and surgical aortic valve replacement can improve symptoms and survival. In recent years, transcatheter aortic valve implantation (TAVI) has been demonstrated to improve survival in inoperable patients and to be an alternative treatment in patients in whom the risk of surgical morbidity or mortality is high or intermediate. A representative expert committee, summoned by the Association of Cardiovascular Interventions of the Polish Cardiac Society (ACVI) and the Polish Society of Cardio-Thoracic Surgeons, devel-oped this Consensus Statement in transcatheter aortic valve implantation...

A 62-year old male with pulmonary fibrosis and aortic valve stenosis underwent TAVI (Corevalve Evolut XL 34 mm) in the build-up for lung transplantation (LuTx). Following post-dilation for a large annular perimeter, moderate paravalvular aortic regurgitation (AR) was observed. After 6 weeks, he was admitted to the ICU with respiratory failure(A). TTE demonstrated residual mild AR (based on a small excentric paravalvular AR jet, <10% circumferential extent, pressure half-time was not reliably measured) and together with borderline elevated NT-pro-BNP, the consultant cardiologist authorized LuTx listing...

Transcatheter aortic valve implantation (TAVI) has been widely used for the treatment of aortic stenosis. Most pivotal studies of TAVI included patients with a mean age of over 80 years old. Many young patients may also be considered for TAVI because of severe co-morbidities. We sought to describe a group of patients undergoing TAVI at an age below 70 and to compare them with older patients undergoing the procedure. This study included 1,324 consecutive patients from a 3-center TAVI registry from 2008 to 2014...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a well-established treatment for patients with severe aortic valve stenosis. This procedure requires pre-operative planning by assessment of aortic dimensions on CT Angiography (CTA). It is well-known that the aortic root dimensions vary over the heart cycle. However, sizing is commonly performed at either mid-systole or end-diastole only, which has resulted in an inadequate understanding of its full dynamic behavior. STUDY GOAL: We studied the variation in annulus measurements during the cardiac cycle and determined if this variation is dependent on the amount of calcification at the annulus...

Lower vagal activity is associated with psychopathology independent of age. Research suggests that alterations of vagal activity precede the development of psychopathology. The present review aimed to quantify sex differences in vagal activity in children and adolescents. Studies reporting on sex differences on measures of vagally-mediated heart rate variability derived from short-term recordings under resting conditions in boys and girls were included. Drawing on data from more than 5,000 children and adolescents, we provide evidence that healthy young girls display lower vagal activity and greater mean heart rate compared to boys, a finding that may have implications for risk associated with the development of internalizing psychopathology and somatic ill-health...
